History:
The project began in September 1944, when Nakajima was entrusted with the development
of a jet powered signal seat bomber. Designed by Kazuo Ohno and Kenichi Matsumura,
the aircraft was to be able to deliver a 500 kg bomb at 700 km/h with a range
of 900 km as well as having folding wings to enable it to be hidden in caves
and tunnels. The engines used were Ne-20 turbojets which were hastily built,
based on the BMW 003 turbojet. Two prototypes were built between June and August
1945. The first prototype was ready by the beginning of August 1945, it's first
flight being on the 7/8/1945 (one day after the nuclear bombing of Hiroshima).
Four days later the aircraft had a serious accident This caused the test program
to be stopped whilst the second prototype was being built. At the same time
18 other Kikka aircraft were in various stages of production, including the
two seat trainer "Kikka-K".
